looking at a brute force 750 bored out to 783 and have a set of silverbacks. buddy was blunt about my questions and didnt tell me what year. looks like an 05. dont know much about bored out bikes but iv heard they have more power but they break down alot too. they also blow up quite alot.need some of you guys that know about bored out bikes to let me know.

 

33 cc more is not much of bored out for original 750.
I bored out 50 cc more on my 250 dual purpose bike and it's a daily rider.
With good maintenance and reasonable riding style (such as no sucking in water into air box!), the reliability should be about the same as that of stock 750.
I have a bone stock '05 8-yr old 750 and it's still runs like new - been using Mobil 1 since day 1 and never gone mudding (no mud in So Cal!).

 

well the snow is just melting and i want to get somthing that i can keep up to my buddys with 700's. we have some mud in the spring and fall but its not retarded deep. i live in Canada so i run supreme and my old bike liked supreme and couldn't go anywhere with regular. i talked to a few guys and a lodge last night and they said if i can get a good price to buy it cause bored out that much will give a little more power but i wont cause any problems.

 

If you get the BF750, there is a few stuff, depending on model year, you should upgrade to prevent unnecessary problems in the future.
> Rear buss connector
> Upper A-arm bushing
> Fuel pump/filter
just to name a few.

 

What years would you be talking about Hayashi?

 

I have also heard from a few owners that mid 2000 BF 750 can be a little squirrelly handling at speed on the trails, something to do with the way the front end and suspension is set up. And, not to bash Kawasaki, but I have never been much of a fan of the KAPS drive system, that damn little actuator always self adjusting, and the limit switch that can fail/trip and cause you to go into low power limp home mode. Sorry if I offended any die hard Brute fans. but that is just my opinion, I just prefer a less complicated set up, without all the self adjusting, switch tripping stuff.

 

Depends which problem you are referring to...

I updated the info below:

 

Since I have 7+ years of riding the BF750, I may be able to provide some truths to the "opinions".

It's somwhat true but it's not because of the front double A-arm suspension (which is common on other Kawi models), but it's because of IRS with rather higher CG than typical SRS quads. And also typically IRS quads have higher suspension travel than SRS and can't do the hi speed power sliding (drifting) as well as the SRS. If you are used to riding SRS, then the IRS will make you nervous at first when riding fast on trails.

Yep, it makes the whining noise all the time, doesn't it?!
The EBC (Engine Brake Control) actuator is not really self-adjusting but rather going back to its home position after activation (getting away from the home position and pressing against the drive converter center bearing to squeeze on the belt).

Yep, if that belt failure detection toggle switch inside the CVT cover trips on you, your quad speed is limitted to 5 mph only in order to protect you from trying to go too fast and get you in a trouble - the stretched belt can snap at high speed and wrap around the cvt converter locking it up and bringing the quad to instant stop. It's safety feature. If you maintain your cvt belt in a good shape by not abusing it, the switch would not trip. Mine hasn't tripped not even once in 7 years and 2000+ miles on a same factory original belt.
